2 pictures spectra of wrapped strings. The 1. is measured spectrum, A1 =
(54.2 Hz)of a Seiler 116 upright. The 2. spectrum is the same note =
computed with MiniMens with the measures of this piano with a string =
length 1086 mm, core diam. 1.1 mm wrap diam. 1.4 mm blank ends 20 mm. =
The regular lines are the transversal waves. Additional spectral lines =
due to longitudinal waves (1. longitudinal wave on the 13. transversal) =
and caused also by blank ends reflection of longitudinal/ transversal =
waves.
